Guide bar support for concrete gauges



Aug. 21, 1934. s. E. SCOTT GUIDE BAR SUPPORT FOR CONCRETE GAUGES Filed Dec. 14, 1932 INVENTOR,

ATTORNEY Patented Aug. 21, 1934 hire s'rATEs .r ics This invention relates to improvements in guide bar supports for concrete gauges. An object of my invention is to provide im- W proved supporting means of the character indi- 5 ca ted which is adapted to maintain guide bars in certain fixed positions during the laying of concrete floors.

Another object of my invention is to provide a.

, W reversible guide bar supporting bracket which is capable of being used to provide a support located beneath a guide bar or a support wherein the guide bar is held in a suspended position.

It frequently. becomes necessary after a concrete floor is laid that additional concrete ma- -16 terial be distributed thereon to provide either a higher uniform surface or a surface which is partly elevated above the main floor. At the present time there are no guide bar supports adapted for use in maintaining concrete gauges in their proper positions during the pouring of a concrete floor and whi h may also be utilized to maintain guide bars or barriers in suitable positions during the resurfacing of the main concrete floor. With the present invention it is possible to position my improved guide bar supporting bracket so the concrete gauges or levelers associated therewith may be maintained in proper positions during the pouring of a concrete floor, and later reverse the original position of the bracket and effect the supporting in a suspended position of guide bars or barriers used during the resurfacing or treating of the concrete floor. My invention therefore provides apparatus capable of serving the dual purpose of providing a suitable support for guide bars and also a means for maintaining guide bars or barriers in proper positions during the resurfacing or refinishing of floors.

Another object of my invention is to provide an adjustable guide bar support provided with novel and conveniently manipulated adjusting means located in a position which is readily accessible without danger of disturbing the poured concrete flooring.

Other objects more or less apparent will present themselves or will be specifically pointed out in the description to follow.

In the accompanying drawing:

Fig. 1 is a side elevation of guide bar supporting device constructed in accordance with my invention, showing a guide bar and a portion of the flooring structure in section;

Fig. 2 is a front view of the device shown in Fig. 1;

Fig. 3 is a top plan view of the same;

Fig. 4 is a rear view of the same; and

Fig. -5 is an enlarged vertical section of a part of the device showing the adjustable means for maintaining the bracket on the post.

.Referring to the drawing, the numeral 1 designates a standard .or post, provided at one end with a reduced threaded portion which is ordinarily attached by a wing nut 2 or other suitable means to a flooring structure 3 over which concrete material is to be poured. Slidably. and adjustably mounted on the post 1 is the bodyportion 4 of a bracket having a vertically disposed. opening 5 extending therethrough whichis enlarged and threaded at one end as at 5. Screwed into the enlarged end 5' of the opening through the body portion of the bracket is a locking nut 6 having an eccentrically disposed'vertical opening therein through which the upper part or the post 1 extends. Theopening through'the locking nut .6 is adapted to be valigned.withthe opening 5 in the body portion 4 of the bracket when the 115 said nut is turned to a certain position, thereby permitting the said bracket to be placed upon the post 1. In order to secure the bracket in a certain position on the post the locking nut 6 is turned a part of one revolution, thereby carrying so the opening therethrough out of registry with the opening 5 and causing the sides of the openin of the nut to firmly press against the post and frictionally maintain the said bracket in a temporarily fixed position thereon.

The bracket also includes a cradle or hook portion 7 which is formed integrally with the body portion 4, the said cradle portion being suitably shaped and proportioned to receive a guide bar 8. In ordinary practice the guide bar 1 is held in a suitably supported and substantially horizontal position by a plurality of gauges of the type comprising the present invention. After the gauges have been properly adjusted so that a plurality of spaced guide bars may be suitably supported above the flooring structure 3,

a number of leveling bars are placed across the guide bars. The leveling bars are then employed to indicate the top surface of the concrete flooring, which ordinarily is positioned immediatelybeneath the lower edges of said leveling bars.

Extending through an upwardly projecting part 7 of the cradle '7 is a set screw 9 which is employed to securely hold the guide bar 8 within the confines of the said cradle. The downwardly, disposed part 7a of the cradle is provided with a short flange 7b which engages with the post 1 and serves as a brace for the bracket when operatively positioned on the post.

After the concrete flooring has been poured 1 and formed, the posts 1 may be removed from the flooring structure 3 by unscrewing the wing nuts 2, thereafter permitting the withdrawal of the said posts from the wet concrete. Should it be desired to resurface the concrete floor the brackets position on the post may be reversed, thereby permitting the guide bar to be held in a suspended position where it may directly contact with the said floor and serve as a barrier for material placed thereon.

It is obvious that various changes and modifications may be made in respect to the details of my invention as the sameis shown and described herein. For this and other apparent reasons I desire that the appended claims definethe limits of my invention rather than the exact disclosures herein made.

Having described my invention what I claim is:

1. A guide bar supporting device comprising a post having means at its lower end for attachment to a structure over which cementitious maing an end'oi the post, the said locking nut being adapted tobe turned in the threaded opening to cause a binding engagement with the post. 7

2. A guide bar supporting device comprising a post, a bracket having a vertical opening through which the post extends, the said opening being partially enlarged and tapped at one end, and a locking nut screwably mounted in the tapped opening in the bracket having an eccentric opening through which the post extends, the said nut being capable of being turned to effect a binding engagement with the post.

3. A guide bar supporting device comprising a post, a bracket having an opening therethrough within which the post is normally positioned, one end of the said opening being enlarged and tapped, and a locking nut adjustably screwed into the tapped end of the opening, having an eccentric opening therethrough within which the post extends, the said nut being adapted to be turned to cause a binding engagement'with the post.

4. A guide bar supporting device comprising a post having means at one end for attachment to a structure overwhich cementit'ious material is adapted to be poured, a supporting bracket have ing an' opening therethrough within which the post is normally positioned, one end of the opening being enlarged and tapped, the said bracket having a flange thereon engaging with a side of the post, and a locking nut screwably mounted in the opening in the bracket having an eccentric opening through which the post normally extends, the said nut being adapted to be turned to cause a binding engagement withthe post.

5. A device of the class described comprising a pcst,-a' bracket having an opening through which the post extends, one end of the opening being tapped, and a locking nut screwably located in the tapped end or" the opening in the bracket, the said locking nut having a threaded periphery and an opening therethrough for re ceiving an end or" the post, the said opening in the nut being eccentrically disposed with referenceto its threaded periphery, the said locking nut being adapted for binding engagement with the post.
